Engineering Guidelines

Other IP phones, however, do not support compression. Calls to and from these devices are
restricted to G.711 only. The following IP phones have this restriction:
•
4015 and 4025
•
5001 and 5005
•
5201, 5205, and 5207
3300 ICP controllers and compression
A single controller has the following limitations:
•
If the controller has one compression DSP module, the maximum number of compression
sessions is 32. If the controller has two compression DSP modules, the maximum number
of compression sessions is 64.
•
If the controller has DSP-II fitted, this is capable of up to 64 compression sessions per
module.
•
No more than 999 compression zones are possible from a single MiVoice Business/ICP
system.
•
E2T compression is used primarily to deal with TDM devices such as ONS phones or PSTN
connections.
•
At Release MCD 5.0, the 3300ICP can only terminate calls with G.711 or with G.729 com-
pression CODECs. Termination of G.722.1 connections is not provided, although the
3300ICP will handle through negation of the G.722.1 connection between end devices.
Internal 3300 ICP devices and compression
Conference
The conference feature is based on G.711 format, and is considered a TDM device.
Compression is needed in the 3300 ICP to communicate with each IP phone that normally uses
compression to a TDM device.
Voice Mail
Internal Voice Mail stores data in G.711 format, but compression can be used to and from this
device. An IP phone that uses compression to a TDM device uses compression to the voice mail.
Music On Hold
Music-on-Hold (MOH) can be sent with compression (at the expense of audio quality). Each
MOH session to an IP destination uses a compression license.
Note:
The dual DSP module used on the CX can support a maximum of 16 compression
sessions.
